Description

A kind of writing Nearsightedness-preventing pen

Technical field：

The invention belongs to Writing instrument field, more particularly to a kind of writing Nearsightedness-preventing pen, in particular by low level battery compartment The Nearsightedness-preventing pen of design.

Background technology：

With the development of microelectronics, significant progress also occurs for electronics Nearsightedness-preventing pen last decade, on penholder top from upper Battery, upper axle bed, the circuit board with infrared sensor, actuation coil, lower axle bed and throw-out lever are sequentially distributed under and；Student makes With this writing process, when face gets too close to desktop, at this moment built-in infrared induction circuit can receive anti-by face It is emitted back towards the signal come, is dealt with by circuit judges, control coil is powered or power-off, and coil, which is powered, generates magnetic field suction thrust Magnet on bar makes throw-out lever up tilt, and at this moment pen core is just retracted upwards in the case of no rear support power, and the pen is with regard to nothing Method is write, and myopic-preventing protection is formed；When desktop leaves to certain distance in face, then throw-out lever resets, and has support at the top of pen core It can normally be write after power, reach pre- myopic-preventing effect.

Currently, the battery of such Nearsightedness-preventing pen is installed in pen arm end, battery is replaced for convenience, is set in pen arm end It is equipped with a pen cap.Due to high density button weight weight, somewhat top-heavy sense when holding a pen, the especially small supporting point of student's palm is inclined It is low, it is this to feel to become apparent.The deficiency for how improving existing Nearsightedness-preventing pen becomes the object that the present invention studies.

Invention content：

The purpose of the present invention is a kind of battery compartments of design, and the writing Nearsightedness-preventing pen between lower axle bed and coil is arranged.

The technical scheme is that be achieved：A kind of writing Nearsightedness-preventing pen, include penholder, pen cap, nib and Pen core；Penholder top be sequentially distributed from top to bottom upper axle bed, the circuit board with infrared sensor, lower axle bed, actuation coil and Throw-out lever；It is characterized in that：It is provided with battery compartment between lower axle bed and actuation coil, is mounted on battery the two poles of the earth pair in battery compartment It should be electrically connected with lower axle bed and upper axle bed.

The lower axle bed and actuation coil are arranged on a core print seat plastic, the core print seat plastic lower axle bed and actuation coil it Between battery compartment is set, the battery compartment be across penholder central axes longitudinal grooved, be provided in an elongated slot middle side part of fluting negative Pole lead is provided at both ends with cathode stage portion, and a short slot side of fluting is provided with positive wire.

The penholder includes Pen-holder sleeve and penholder core, and penholder core is made of transparent sheath and core print seat plastic, and core print seat plastic plugs In transparent sheath lower end；Upper axle bed and circuit board with infrared sensor are mounted in the transparent sheath, and penholder core is by transparent sheath Lower end is plugged in the Pen-holder sleeve upper end, and the infrared sensor on holding circuit plate exposes outside.

The battery bin location that the Pen-holder sleeve corresponds to core print seat plastic offers gathering hole, which is configured with a lid.

A decorative ferrule is provided between the Pen-holder sleeve and the transparent sheath of penholder core, which is embedded saturating Bright to put on, displacement can block the engaging portion of transparent sheath and Pen-holder sleeve downwards, and keep off toward outside the battery compartment of core print seat plastic.

The present invention moves down battery compartment, has the advantages that：1, penholder decentralization, it is more steady to hold a pen；2, infrared Sensor moves up, and closer to face, reduces sense blind area, reaction is more sensitive；3, it is convenient to assembly and the later stage replaces battery behaviour To make, the transparent sheath bottom of penholder only needs fit on axle bed, and when replacing battery, only it need to open lid or draw penholder core Go out one section, you can operation.

Specific implementation mode：

Referring to FIG. 1, FIG. 2 and FIG. 3, Nearsightedness-preventing pen is write, includes penholder 1, pen cap 2, nib 3, pen core 4, Yi Jibao The pen cap 5 of shield effect；Penholder 1 includes Pen-holder sleeve 11 and penholder core 12, and penholder core 12 is by 122 groups of transparent sheath 121 and core print seat plastic At；1 top of penholder is sequentially distributed upper axle bed 13, the circuit board 14 with infrared sensor, lower axle bed 15, battery compartment from top to bottom 16, actuation coil 17 and throw-out lever 18,4 end of pen core contradict on throw-out lever 18, and rear branch when writing is provided by throw-out lever 18 Support force；The upper axle bed 13 is fixed on the top of transparent sheath 121, and lower axle bed 15, battery compartment 16, actuation coil 17 and only Push rod 18 is arranged on core print seat plastic 122.Battery compartment 16 is set between lower axle bed 15 and actuation coil 17, is mounted on battery compartment 6 the two poles of the earth of battery in 16 are corresponded to be electrically connected with lower axle bed 15 and upper axle bed 13, provides circuit board 14 working power.

Core print seat plastic 122 is plugged in 121 lower end of transparent sheath, and 14 activity of circuit board is placed on upper axle bed 13 and lower axle bed Between 15 so that the circuit board 14 of 13 sum of upper axle bed is in the transparent sheath 121；Penholder core 12 is inserted by 121 lower end of transparent sheath It is located at 11 upper end of Pen-holder sleeve, and the infrared sensor 141 on holding circuit plate 14 exposes outside, so as to infrared sensor 141 It can send out and receive the infrared ray being reflected back.

Such as Fig. 3, battery compartment 16 directly molds on core print seat plastic 122, is the longitudinal grooved across penholder central axes, It is provided with negative wire 61 in the middle part of an elongated slot side of fluting 161, is provided at both ends with cathode stage portion 162, one in fluting is short Slot side 163 is provided with positive wire 62.By cathode stage portion 162, the guiding of positive and negative anodes when battery 6 is installed is provided, pole is avoided Property is reversely packed into.

Such as Fig. 1 and Fig. 2,16 position of battery compartment that Pen-holder sleeve 11 corresponds to core print seat plastic offers gathering hole, which matches It is equipped with a lid 7, it is conveniently replaced battery 6 to open lid 7.

Or such as Fig. 3, a decorative ferrule 8 is provided between Pen-holder sleeve 11 and the transparent sheath of penholder core 12, the decorative ferrule 8 Activity is embedded in transparent sheath 121, and displacement downwards can block the engaging portion of transparent sheath 121 and Pen-holder sleeve 11, and keep off toward core print seat Outside the battery compartment 16 of plastic, when replacing battery 6, only decorative ferrule 8 need to be moved up.

Other than above two structure, can also penholder core 12 directly be extracted into 11 1 sections of Pen-holder sleeve, after exposing battery compartment 16, Battery 6 is more finished changing again insertable into place.In this structure, 11 diameter of Pen-holder sleeve is greater than the diameter of battery 6.
